Muscle System pda human anatomy and blood peredarah system in the human body
1 . MUSCLE SYSTEM
The muscular system is the body system that has fugnsi like to tool motion , determine the store glycogen and body posture . Consists of smooth muscle , the muscle jantungdan rangka.Arti muscle definition / understanding Network is a group of cells that have the shape , structure and function the same . So the muscle tissue is a group of muscle cells . To move our limbs , muscular system is needed . The muscular system is composed of several parts separated from each other called muscles . Most of the skeletal muscle kitamelekat . Muscles can contract and can also be tightened . Olehkarena , muscle arrangement is a system tool for control of active motion and posisitubuh us . At every muscle seen some jerked the active part mengerut.Otot is active locomotor able to move the bones , skin danrambut after receiving stimulation . Muscles have three special abilities are:
Ø kontraktibilitas : the ability to contract / shorten 2 . Extensibility : the ability to perform the opposite movement of gerakanyang generated during contraction
Ø Elasticity : the ability of the muscle to return to its original size after contraction . When returning to the original size of the state of muscle relaxation disebutdalam According to its location , the muscle can be divided into the muscles of the body trunk , limb muscles and the muscles of the head . Body trunk muscles consist of the abdominal muscles , back muscles , chest muscles and neck muscles . Back muscles are not visible from permukaantubuh . Back muscles function to spinal movements . Terentangantara abdominal muscles and the pelvic girdle to the chest . These muscles can be shortened actively .
According to the type of muscle while essentially consists of :
A. The parts of muscle :
· Sarkolema : the membrane that lines the muscle cells that function as a protective muscle
· Sarcoplasmic : liquid muscle cells whose function is to be a place where myofibrils danmiofilamen
· Myofibrils is in the muscle fibers .
· Miofilamen : benang-benang/filamen refined from myofibrils . Miofibrilterbagi on 2 kinds , namely : miofilamen homogeneous (located on smooth muscle ) danmiofilamen heterogeneous (located in the heart muscle / muscle and in skeletal muscle cardiak / ototlurik ) . Miofilamen In the kontaraktil proteins are called aktomiosin ( aktindan myosin ) , and tropomyosin tropopin . When muscles contract ( shorten ) the protein actin is working and if we do a muscle relaxation ( lengthening ) the myosin at work .
Muscle tissue consists of : 1 . Plain muscle ( voluntary muscles )
· Other names : muscle tools in / visceral / musculus nonstriated / involuntary muscle
· Structure : long fibers such as coil shape , with a pointed end , amounted to one located dibagiann denganinti middle .
· Contraction : not according to the will or outside the control of the central nervous system , slow motion , rhythmic and not easily tired .
· Smooth muscle is one muscle that has a smooth shape and bergelondong . How it works is not realized ( not as desired ) / invontary , has a nucleus which is located in the center of the cell . This muscle is usually a digestive padasaluran such as the stomach and intestines .
Circulatory system
Human circulatory system is composed of the heart as the center peredarandarah , blood vessels and blood was sendiri.A.JantungJantung has four chambers : two perfect split foyer ( the atria ) and two chambers ( ventricles ) and is located in the upper chest cavity sebeh .
a) DarahPembuluh blood vessels consist of arteries and veins . Denganvena directly related artery in the capillaries and venules are connected by a section of its endothelium . Located adjacent arteries and veins . Artery walls thicker than vein wall . The walls of arteries and veins have three layers , namely the inner layer which Consist endothelium , the middle layer is composed of smooth muscle with elastic fibers danlapisan outermost consisting of connective tissue coupled with elastic fibers . Cabangterkecil of arteries and veins called capillaries . Yangsangat capillaries have a diameter small and only has a single layer of endothelium and a human circulatory basal.Sistem membrane consists of :

· Atrium kiri.Atau : Heart
· Lungs
